The 6.5mm UTC was designed by Wes Ugalde for use in his Thompson Center Contender. This cartridge was initially developed for use in Metallic Silhouette Competition but has found considerable success as a varmint handgun chambering. The 6.5mm TCU is easily converted from commercial 223 cases by simply running a tapered expander through the case neck. Fireforming is accomplished with a slightly reduced load. Silhouette shooters have found that this cartridge is marginal for topping the distant ram target; some hits do not result in a felled target. For this reason popularity has been limited in that sport. The 6.5mm TCU does, however, provide excellent varmint results with comparatively mild recoil.
